They replayed the episode with the house inherited by the young woman again last night. This is my favorite episode so far. Erin talked about having the two-toned house, but didn't explain why they did that. I'd bet it was because the original house had a narrow clapboard but the porch, which had been enclosed later, had a wide clapboard. With the whole house the same color, it made it look odd to have mismatched clapboards. But by painting the two clapboard styles different colors, it highlighted the difference and made it look very intentional. Brilliant solution!
